Tattooed Assasins

In the early nights of the wars of the mortal races buried deep in the recesses of creation lied the art of mystical inks being inlaid into the skin of those that were worthy of the ink. The origins of the ink is still a mystery to this day and many speculate it came from Asmodeus himself, some speculate that an angel from the heavens bestowed the ink to level the playing field. Regardless of how the ink was found, or came to be, the one thing that is understood that not everyone can bare the ink in their skins, and often times a new recruit to the line are killed in the process of applying the ink. 

In the early days it was said that rival houses had access to the inks that allowed a multitude of warriors to brand their skins with the power of the inks, but as it would turn out that in present times the inks are exclusive to an order of assassins that are for hire to many different crime syndicates, crown, or just the highest bidder. No one outside the order of the Assassins truly understands the properties of the inks or how they even work.

The inks has a price, the powers given to the assassins come at a cost. The more tattoos the assassin gets the deeper into madness the assassin falls into. There is always a cost to power, originally the assassins were your common rogues that wanted more, much like warlocks they apply these tattoos to gain that power. Although unlike the Warlocks their Inks are not patrons and they do not request favors or demand servitude in some cases. No no the ink takes more, as the inks becomes more prevalent in the skin it draws on the mind of the assassins. Each assassin is regulated to a certain amount of tattoos that will keep them from going completely mad and insane. Although that doesn't mean that one can not go beyond and when this happens the assassins become unstable. Much of the order despite the ideals that they kill for money or favor or trade, believe in balance, in fact it is their most important teachings. When an assassin starts to delve to deep into the ink; or called an Inked mind, they hunt the assassin till he no longer drawls breath. 

Inked Mind effects

When a Tattooed assassin goes beyond their mental means they start to develop mental afflictions that can not be cured by magic, unless the tattoo is either carved out or pulled out of the skin through magical means. In addition the Assassin also loses the following. 

 

Extra Tattoo	Effects	Secondary effects
1		Derangement
2	-1 to Either Int or Wis Score
3	-1 to Int and Wis Score	Derangement
4	-2 to Int and Wis Score
5	-3 to Either Int or Wis Score	Derangement
6+	-4 to Int and Wis Score	Derangement

 

Being reduced to a 0 in any stat kills the character, DM's should not encourage additional tattoos, and should impose serious Derangement's and enforce the severity of trading ones soul and mind for power. After the second extra Tattoo, through mystical senses the Order can sense the assassin with in 10 miles of their location.  It is at that time the Assassin becomes hunted by the order.

When you set out from the order you have enough ink to create the given tattoos you gain through leveling up. Taking additional tattoos will require you obtaining additional vials of Mystic ink eventually down the line. It is the DM's desecration if you pay for additional or you are given, if forced to pay one vial runs 500 gold pieces.
